Sophie is my very first dog EVER!!!
However, when I first started dating my now DH, he had a Great Dane. She lived another 4-5 years. She was the BEST dog. She listened to my DH, but she loved me!
We sadly had to have her PTS due to serious health problems when she was 12 years old (old for a GD). It was a very hard thing to do and I still miss her.

Sooooo... going from 150 lb. dog to a plump 10 lb. dog (yep Sophie is a teapot) is quite a big difference.
